Everyone knows the Miami Dolphins need a No. 1 receiver, and there are three in the 2013 free-agency class.

Greg Jennings is reciprocating the interest (h/t Ben Volin, The Palm Beach Post), but is he Jeff Ireland's top choice? If he is, a deal may be consummated shortly after the free-agent signing period begins.

Mike Wallace and Dwayne Bowe are younger options than the 29-year-old Jennings but will likely be more expensive.

The truth is Miami has the means and desire to land one of the "Big Three." This is the core of the Dolphins' plan, and if it falls through, Miami's offseason will be a failure.

On the bright side, it is very likely, making mock drafts where Miami drafts a receiver in the first round baffling.

Speculation No. 2: Miami Will Re-Sign Brian Hartline

He is also the second ingredient needed to transform the Dolphins' passing game from subpar to high end.

Hartline's asking price is rumored to be $6 million (h/t Barry Jackson, The Miami Herald). Ireland may be able to land the stud No. 2 receiver for a little less, but make no mistake, Hartline is a priority for Miami.

Anthony Fasano has been a steady performer for the Dolphins, but Miami has a chance to upgrade this position in free agency with tight ends such as Jared Cook, Fred Davis, Dustin Keller and Martellus Bennett.

The Green Bay Packersmay release Jermichael Finley, a player that Miami coach Joe Philbin is familiar with. Finley meets the criteria of a tight-end upgrade but has been inconsistent and outspoken about disagreement with his team's game plan.

Luckily for Miami, Philbin has insight on this matter, and a decision on whether to pursue Finley has likely been made already.

Even if it is not Finley, the Dolphins have money to spend on a position that is important for the success of Ryan Tannehill. Expect one of the top free-agent tight ends to ink a deal in Miami.

Speculation No. 4: Miami Will Re-Sign Sean Smith

Buzz Stock: Sell

While the Miami Dolphins would love to have Smith back, it will have to be at the right price. Armando Salguero of the Miami Herald reports that Smith is seeking $8 to $10 million per year (h/t Armando Salguero, The Miami Herald). Jeff Ireland and the Dolphins will never pay that price.

Smith is a good cover corner but does not have good hands, making only five interceptions in four full seasons. The 2013 free-agent cornerback market is full of able players with question marks, of which many would sign for significantly less.

Smith has not separated himself from a group that includes Brent Grimes, Chris Houston, Cary Williams, Derek Cox and Dominique Rodgers-Cromartie, among others.
